ITV’s Betrayal finale airs tonight with viewers already asking if there will be another series.
Betrayal is drawing to a close and viewers are already wondering whether the ITV espionage thriller will return for another season.
Endeavour star Shaun Evans takes centre stage in this gripping four-part series, portraying MI5 officer John who uncovers an imminent attack on British soil.
His complex inquiry, coupled with marital turmoil at home, has delivered riveting television over the past fortnight, with the concluding episode broadcasting tonight, Monday, February 16, on ITV.
Will Betrayal return for a second series?
At present, there has been no official announcement regarding Betrayal’s renewal for a second series.
For viewers who have already devoured the drama on ITVX, this inaugural series does conclude the narrative, leaving no significant unresolved threads for Betrayal to explore in a potential follow-up.

Nevertheless, this doesn’t automatically rule out Betrayal’s comeback, as a second series could instead centre on John becoming embroiled in other high-stakes investigations.
There’s also the matter of John’s marriage to Claire (Romola Garai) remaining uncertain in the closing moments as they resumed couples’ therapy.
Actor Shaun Evans revealed that whilst no plans exist for another series, additional episodes could materialise if Betrayal resonates with home audiences.
“We set out to make a four-parter which was strong and felt like it had no filler, that it wasn’t hanging around, that it was tight and concise, and that the story was really strong,” he told Radio Times.
“And then you offer that to the world, and if there’s an appetite for more, then we will get together and discuss whether there’s more story to tell.
“But it wasn’t like, ‘This is a brilliant setup for running and running and running’.
“I think you’re on a hiding to nothing if you do that. To me, it feels quite cynical.”
For the time being, however, viewers will simply have to remain patient to discover whether additional episodes are in the pipeline.
Whilst Betrayal’s complete boxset has been available to stream on ITVX since last week, its concluding episode will premiere this evening, Monday, February 16, on ITV.
But can Mehreen and General Qasem Asadi (Omid Djalili) be relied upon, or could a potentially fatal attack actually be on its way?
Betrayal is available to watch on ITVX.
